Window & Wall Ventilators

Passivent’s Aircool® range of controllable, insulated wall and window ventilators are designed primarily for use in external facades but can also be used within buildings. They work with all forms of wall construction, curtain walling and window profiles. They offer superior thermal performance with a U-value as low as 0.86W/m²K when closed. Electrically actuated modulating dampers provide controlled air intake and extract in natural or mechanical ventilation systems and they are virtually silent in operation. Excellent weather protection and security are provided by the external weather louvre, even when the insulated damper blades are open, and the internal cover grille protects against impact damage in areas such as sports halls. Both louvres and grilles can be colour matched to any RAL or BS colour. Thermal, acoustic and hybrid air mixing variants are available to attenuate noise or treat the incoming air in various ways as required by the user.
